The bad news about doing it this way is that the video memory usage is going to be large if you use a lot of large bitmaps. That 1600x1200 black panel was around 8MB when active. My fullscreen filmgrain effect(from another contribution) clocks in at around 49MB(6 1600x1200 PCX files).



Of course! A captured 1024x768 screen makes ~3,4 MB more or less, that is very much, indeed.

I don't know how you do your effect, but it could be worth it when you dont adapt it on the current screenresolution but on a bitmap that is smaller so that you work on it and later you scale it. 49MB for an effect with 6 1600x1200 files is a waste of memory! Can I have a look at that other contribution because I dont get the clue what are you talking about.
